Unless statet other by the rules all inputs should be allowed, if you are unsure ask in the forum of the game.

Danke, yes, I suppose it is a better idea. Maybe this thread can be removed.

I was trying to edit this post, but deleted my first one. Here is the original message.

"Hi, well I do not consider myself a real speedrunner but I have two submitted runs, and I played both on a keyboard. Well I have two keyboards. However I could not found anything about this in the rules, but are you allowed submit runs that are played on a keyboard, a d-pad with usb-connection or a joystick or even a hitbox? Sometimes I play with a d-pad as well, I think htey are rather equal, but maybe keyboard is a bit more ergonomic, not sure though."
